Add Actions pane

This view will contain actions to be performed as part of the database tests.

present retrieved information in a separate view (possibly window) for
the user to check.
Add Connection settings pane

This view will contain settings specific to each of the databases tested,
as well as the connection parameters used for the connection and (later on)
data retrieval.
